Ever since installing Big Sur, whenever I shut down and then restart my computer, the wallpaper changes from my selection back to the default. I am using an external display (1080p). Perhaps the new dynamic wallpapers are not meant for this resolution? I tried a still image wallpaper also and the same issue occurs. Is anyone else experiencing this? Is this a known issue?
Thank you,

My solution, at least it seems to work on my Mac Mini 2020 with two monitors attached was to delete de desktoppicture.db in directory ~/Library/Application\ Support/Dock/ and restart. The default background picture appears but after change it in the two monitors and restart, the background selected was fixed.
Hope can help.
No, I don't have 'auto log-in' enabled. Just 2 accounts (one admin, one standard), where I have to log-in with password.
As I told, only have problems when I log-in to Standard account first and then to my admin account, the other way around all is OK. So I really hope Apple can help out with an update to fix all these problems.
Anyway, I will try what "Marc-SmartFactory" wrote.
I deleted desktoppicture.db both in my admin and the other standard account like Marc-SmartFactory suggested above and it worked for me, the wallpaper stays like set before when changing accounts, at least the two times I tested it today.
But of course I still see the Big Sur rainbow wallpaper at log-in.
I have a Mac Mini connected to an Apple Thunderbolt Display (primary) and an Apple LED Display. Never had this issue before Big Sur. I will reset the desktop picture and it will display correctly for several days and then BAM! the big red ugly default picture displays.
And, honestly folks, there are two issues here: 1: the software doesn't work right and it (at least for me) is a new issue specifically with Big Sur; and 2: How in the heck could Apple make something that horrendous as the default desktop? It's truly unpleasant and once I switch to my selected desktop picture, my eyes lag with all my rods and cones overloaded with that red monstrosity. Geez Apple, fix this thing now! Please!
On my Mac Mini, it's the primary monitor that always starts with the ugly default Big Sur wallpaper. The second display is always correct.
I would like someone at Apple to tell me whether I'm stuck with the Big Sur background after restarting by design?

I rarely have the problem anymore and I'm not sure what solved it because I tried so many things. It would seem an idea for Apple to work on it for their next update.
Same issue, even if I let it go to sleep. What ever to happened to ..."It just works"???
Doesn't solve the issue for me on the MBP 16" - it is so annoying...
In addition - the "Catalina" way to change the lock screen wallpaper is no longer working, even withy csrutil disable, I'm not able to change files in "Desktop Wallpapers" folder.
I'm having the exact same issue on my external display. KinTheKnow's answer didn't work for me at first. I followed the instructions he mentioned but then I had to access the settings again to change desktop wallpaper and now 2 windows popped up one on each screen to change wallpaper to each one.
Yep, the same issue. Obviously related to multiple displays and/or multiple desktop. I have two external displays at work and am using multiple desktops at home. Every time I get to work and open my MacBook, I find the wallpaper back to default.
